 near Vladivostok, Japan Sea. 



Head 2f in length without caudal; depth 3|. Dorsal X-16; anal 14; 

 lateral line with 37 pores. Eye 5 in head; interorbital space 8; snout 

 4; maxillar}' 2; height of caudal peduncle 4 to 4^. 



Body anteriorly as wide as deep; head wider than deep. Nape 

 slightly produced above occipital region; a (Conspicuous notch in pro- 

 tile in front of eyes, formed ])y the produced nasal spines. Mouth 

 large; maxillary reaching to below posterior rim of orbit. Teeth 

 villiform, in rather narrow bands in jaws, vomer, and palatines. Pre- 

 opercle with a strongly hooked sharp spine at angle, an anteriorly 

 directed spine at lower anterior edge, and a couple of slight bony 

 tubercles on edge between spines. Nasal spines large and rather 

 sharp, though their tips scarcely project through the skin. Toj) of 

 head with 3 pairs of multitid Haps; the first over posterior border of 

 eye, a little larger and usually more divided than the others; the
